DescriptionThe whole story▼

A touring GSX-S1000 spends enough hours in the saddle to make a readable reservoir useful. LighTech machines the OBT001 from billet and lines it in plastic so 31 cm³ of fluid stays visible. Anodising runs to 2 colours on the OBT001. The listing covers the GSX-S1000 across 12 model years (2015 to 2026).

Key Features

  • Colour is the only choice to make on the OBT001
  • Billet aluminium outer shell, machined from solid
  • Reversible — the original part goes back on the GSX-S1000 any time
  • Translucent plastic liner, so the fluid level on the GSX-S1000 stays readable
  • 2 colours, all at the same price
  • Finish changes the look of the GSX-S1000, not the fit

Looking After It

Fluid darkens as it absorbs water — on the GSX-S1000 that is now visible without tools. Nothing else about the OBT001 wears in normal use.

Why the Original Falls Short

The original reservoir on a GSX-S1000 is opaque, and opaque hides exactly what matters. At 31 cm³ the OBT001 matches the capacity the original reservoir of the GSX-S1000 carries. On the GSX-S1000 the reservoir replaces the original box and nothing else has to move.

Fitment and Compatibility

LighTech lists the OBT001 for the Suzuki GSX-S1000. The reservoir itself is universal. What makes it fit the GSX-S1000 is the bracket and the hose, not the tank.

Mounting It

Fitting the OBT001 to a GSX-S1000 is a hand-tool job. Bleed and pressure-test the circuit on the GSX-S1000 afterwards; this is not a cosmetic part. No permanent alteration to the GSX-S1000 is involved.

What Is in the Box

LighTech ships the OBT001 complete except for the mount. The part number is all you need to quote for a repeat order on the GSX-S1000.

Before You Order

The OBT001 arrives as a tank and a cap, nothing else. The brackets are listed under OBT003, OBT008 and OBT009; they differ in height and projection, not in quality. Ask us before ordering and we will match the bracket to your GSX-S1000.

Approval and Safety

On a GSX-S1000 this component carries brake or clutch fluid under pressure. LighTech does not certify the OBT001 for road use, and neither do we. Have a workshop bleed and pressure-test the GSX-S1000 circuit once the part is on, whatever your inspector says.
